Bathroom walls face the harshest working environment in any building, with constant high humidity, splashing water, frequent temperature changes and long term contact with soap and shampoo residue. Many ordinary lightweight wall panels start to deform, swell, grow mold or even fall apart after 1-2 years of use in the bathroom, forcing homeowners to do expensive full bathroom renovation again. The EPS Cement Sandwich Panel is specially engineered to withstand these extreme humid conditions, maintaining perfect performance for decades even in full bathroom use.
Unlike gypsum-based panels that absorb water easily, the cement facing layer of EPS Cement Sandwich Panel is completely waterproof. Even if you splash water directly on the wall surface every day, the moisture will never penetrate into the inner core. When you install it in the bathroom, you can cut neat slots on the panel to lay all the hot and cold water pipes, shower drain pipes and electric water heater wires, then seal the slots with waterproof filler. After that, you can directly tile on the panel surface with thin-set mortar, no extra waterproof coating is required. The panel’s stable structure will not expand or contract when humidity changes, so the tiles pasted on it will never crack or fall off due to wall deformation. You can also directly hang heavy bathroom fixtures like wall-mounted toilets, shower cabins and double basin vanity cabinets on the panel, no extra wall reinforcement needed. Thousands of real bathroom projects have proven that after more than 10 years of use, the EPS Cement Sandwich Panel inside the tiled wall still stays completely dry, with zero mold growth and zero structural deformation.
